THREAD-FEEDING MECHANISM FOR KNITTING-MACHINES.

Specification of Letters Patent.

Patented Feb. 1,8, 1908.

Original application filed February 4. 1901. Serial No. 46.004. Divided and this application filed January I7. 1906. Serial No. 296.443.

E Be it known that we, WARREN D. HUsE 'and LEON C. HUsE, citizens of the United States, and residents of Laconia, county of Belknap, and State of New Ham shire,

have invented an Improvement in T read- Fee'ding lviechanism for Iinitting-Machines, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawings repIresentinU like parts.

his app `cation is a division of our pending ap lication No. 46,004, led February 4,

1901, or knitting `machine, and the lnvention herein described and illustrated has been divided out from the aforesaid application bythe requirement of the Patent Oice. The present invention relates to mechan- 'is'm'for controlling the feed or su ply of the threafls to the needles of the machine.

In the aforesaid application a complete i A:knit-ting...machine is illustrated and de- A"-'sc'ribed, land that. machine-has for its object '.-the automaticv lreduction of seamless stockings,`-wherein t e entire stocking is knit from A f .zone-.end tothe other, and wherein both plain if -aud ribg-knitting are' performed, the changes `from."o1i e', to the other in each case being `-.madefntirely autor'natically,l and wherein '-alsgdifercnt kinds of thread are used, the hangeffiom' one thread to the other being likewisefperformed automatically.

Stociiin such as made by the aforesaid machine is 35.entf.-No.' '626,864, granted June 1'3, 1899.

escribed in United States Pat- Therstocking there described is com cs ed of a plain'ioot'portion including the eel and -toe1formed'of,a thread or threads of suflicient @size to .withstand the .excessive Wear upon 40. ,these parts, and a'ribbed leg portion which gives 4the requisite elasticity required at this art of the stocking. In forming the ribbed eg a larger number of needles are brought intoaction, and it-follows that unless rovi- 4 5 ,'sion were made to compensate for t e increased number'of stitches thus formed the ribbed leg would be too large and unsightly. To overcome this objection the leg portion is formed ofa thread sufficiently finer than that in the foot portion to compensate for the increased number of stitches, and as a further means of attaining the required comparative size of the foot andl leg portion the slzeof the stitches in the two portionsis also-vaned. The stockingma also have a ortion of the leg, as at thelan e, formedwit plain.

knitting with the required size of thread if desired. In general, the operation of the entire machine upon the stocking is as follows. The stocking is preferably commenced at the 50 toe pouch, the active set of needles in narrowing and widening b eing supplied with a coarse thread, after which the plain knit portion is knit in complete circular courses, preferably by a thread ofdifferent size, and 65. during the formation of such footortion the parts are actuated'at an'increase -s eed until the heel pouch is reached, when t e speed of the machine is decreased, a change to coarser yarn automatically effected, and the heel pouch formed .by narrowing and widening. On completiouof lthe `heel pouch-the plain circular knitting isagain automatically resumed athighspeedachange tofnerthreadbeing madelto constitute anankle portion such ankle portion is desired, orifthe ribbed leg is to be formed directl. onfcompl'etion-of' the heel ouch Athen.' the diall needles-armati:- tomatica ly thrown-inte actionya-lchang:

the inerthreadeected, the speedqo I machine automatically increased; l and @the l size of the stitch changed so as to produce-a i ribbed leg of the requisite elastlcityand weight, the entire operation being automatic and continuous. I

The opliration,andconstruction lfthelentire ma#J ne referred to isfully'fse't forth the aforesaid application No.1; @6,004,- and reference may be ada-thereto for-a; more com-` plete understanding ofi'thedetails of the machine, but as the present invention relates only to 'a portion. of the-mechanism therein set forth, and the operation and -eonstructionis. readily understoodby itself, no more eX- l tended reference will be made to4 the con- 95 struction and operation of-lthe other parts of the machine.

It is obvious that the number of different kinds of thread used bythe machine -may vary as desired, and it.' will be seen that' the 100 mechanism to be'describedfis applicablewithout any change'in principle to a larger number of threads than hereln illustrated, without any change in principle, but :chiefly by the duplication and slight rearrangement of the parts. lAs herein shown provisions are made for the employment of three threads, andl there are accordingly three thread-4 g'uides, one for a lar e orcgarsertllxd used in knitting .theli' and'toe pouches, a` second 110l for a :medium orwfinerwthread used for the body .of'th'e' foot, and .a third 95 a still -ner thread used for the ribbed leg portion. IThe present machine, therefore, contains as herein illustrated, a plurality of threadguides, each on'e under the control of proper devices torput it automatically into and out of operative position at the desired times, and cooperating with each thread-guide is shown a thread catcher which holds the end of the thread 'which is thrown out of action while that thread is' not needed in the knitting, and releases said thread when the same has been moved by its thread-guide into engagement with the neddles for a plurality of stitches, thus avoiding holes where the change of thread is effected.

The invention will be more particularly described and illustrated in the accompanying description and drawing, and more deiinitely pointed out in the appended claims, but while certain specific mechanisms are shown as the preferable embodiment of the invention, still the invention is a broad one and such description is not considered to constitute any limitation of the claims other than required by their terms.

The drawings represent only so much of the machine as is necessary to show the mechanism made the subject of the claims herein.

ig. Q is a diagrammatic view representing the cams and wheels employed in effecting the change of position of the thread-guides and holders or catchers; Fig. 10 is a sectional detail of one of the cam wheels.

The framework of the machine, comprising the side plates A of suitable shape to stand upon the floor, the tie-plate A connecting the side plates and supporting the working parts of the machine, the stands A2 erected on the tie-plate and supporting the crossbars and cap plates A, which in turn support the posts A6 upon which the top plate A7 of the machine is mounted, the cam cylinder B18 with the latch needles c with the jacks c7 for operating them, the pattern chain D driven from the shaft D4, herein illustrated, are all as shown and described more at length in our aforesaid application No. 46,004.

A thread-guide stand T is Vsecured to the top of the cam cylinder B18 by a stud screw t passing through a slot t inthe stand. The thread-guide stand T has projecting upward therefrom a flange T which supports the thread-guide operating devices. A second ilange T2 projects upwardly from the guide standT and supports the frame T3 and the ring 128. The ring 128 is provided with a lower beveled edge, as .shown in Figs. 4 and 8, .and is adapted to surround the circular needles of the machine in a usual and a wellknown manner. The frame T3, which is mounted upon the flange T2, has suitable tracks-or guide-Ways t2, t3, in its lower portion for` the thread-guides t4, whereby the lthread-guides are free to slide lengthwise in a manner to be described.

Each thread-guide preferably cooperates with a thread catcher for catching the thread as it is withdrawn from the needles, and to hold the end thereof as the guide is moved to feed the threads to the needles, the'latter ope-ration being for the purpose of insuring the (proper engagement of the thread by the nee es prior to freeing the end thereof.

' Any number of thread-guides and catchers may be used, as already pointed out, but in the present embodiment of the invention we have shown but three, one for the heel and toe thread, one for the thread used to form the plain circular'web of the foot and ankle portion, and the third for the ribbed leg portion. While the guides and catchers are somewhat dierently disposed, as will appear, they are yet the same in general construction, so that a description of one guide and catcher' will suiiice for a clear understanding of all.

Each thread-guide t4 consists of a slide-bar carrying at its end a guide-tube or eye t5, through which the thread controlled by that guide is passed. The guide-way t3 for the thread-guide is preferably provided with an incline t, and the guide is preferably provided with a corresponding incline t? to cooperate therewith, so that as the threadguide is retracted by its spring t8 to place the thread controlled thereby into position to be fed to the needles, the tubular end t5 of the guide is dropped to carry the thread below the upper ends of the needles as the latter rise to take it.

. projection from the angc T of the thread- .spring t8 .will be moved endwise, outwardly Vthe supporting frame T3.

The outer end of each thread-guide is con-v nected at t to a lever t1, pivoted at t to a guide stand T, below a stud t, also projecting from said flange T. The stud tl2 carries a toothed Wheel t13 to the inner side of which is secured a face cam t, a spring t15 -being interposed between a ange T and the hub of the cam to prevent too easy movement of the cam and toothed wheel on the stud and to act as a friction brake. The levers t1? are each provided with a toe t, which under the stress of the springs ts a'ie normall pressed against the face cams t. It willy thus be apparent that if the high part of the face cam t is brought into position to engage the toe t the upper end. of the lever tlo willbe forced inward toward the needles, and the threadguide t* will be moved endwise up the incline ts to carry the tubular end t5 of said guide upward and within the circular row 'of needles. If the low art of the face cam tu is brought into position opposite the toe t1 the thread-guide t4 under the action of its over the top of the circular row of needles, and as the incline t7 of the guide passes the ineline t the tubular end t5 of the guide carrying the thread will drop below the tops of the lifted needles and in position to supply thread thereto, as shown 1n Fig. 8.

Coactiw with each thread-guide t* is a thread catcher comprising a slide arm smovable lengthwise in suitable guideways sf, s', in the supportinF frame T3, and normally pressed outward by the spring s, connected at one end to a in s3 on the slide arm, and at the other en to a pin s* on At its inner end each side arm s is provided with a slot S5 which engages the upper end of an arm s", suitably sleeved on a shaft s", secured to a. suitable supporting frame S, rigidly mounted in any ap roved manner on the ange T2, and as shown y a screw bolt S. The lower'end. of the arm s is formed as a sleeve with a portion on one side cut away at s, thereby converting said sleeve into a sleeve cam. On a shaft $9 below the said sleeve cam is mounted to turn loosely Aa clamping sleeve formed with a ilange or thread catcher s1, the u per end of which has a portion s adapte to bear upon the sleeved cam sa. The lower wall of the support S is continued beneath the series of catchers, and its edge is preferably notched to present guides S12 which, as the tubular end of the thread-guide moves inward and u ward serves to direct the end of the thread eneath the catcher s1".

The outer end of each slide arm s is connected to an actuator or lever s, at s, the said lever being connected to the flange T by the same pivot t that supports the lever t1, and it is provided as at S15 with a toe adapted to engage a second face cam s mounted on the stud of the toothed wheel t, This cam s1 is not directly in line with the cam t, so that in the rotation of the toothed wheel t13 and cams connected thereto the thread-guide is permitted bythe relations of said cams to move outwardly under stress of its s ring ts to carry the thread to the needles before the thread cat'cher is moved outwardly to ree the end of the same thread, thus insuring the engagement of the thread with the needles and the formation of several stitches prior to releasing the end of the thread.

It will be evident that on the rotation of the toothed wheels t13 the thread-guides t4 will be actuated tosupply thread to the needles and thereafter the catcher Icooperating with its thread-guide will be operated to release the end of the thread. It will also be evident that when the threadguide is actuated to withdraw the thread from the needles it will thereupon be caught by the proper catcher, the end -being retained beneath the threa'd 'catchen The parts remain in their thread supplying or non-supplying position until such time as the change is desired to be made.

In order to actuate the toothed wheels t13 at the desired times to supply or Withdraw the thread, a suitable pattern mechanism is provided, and is herein shown as a pattern chain D, having a series of risers or projections which act through intermediate devices u on ins passing through holes in the topa-te X7 of the machine to lift them so that t ey will project into the path of the teeth on said toothed wheels, `and turn the same as they are carried around by the cam cylinder.

More specifically considered the above results are e'ected by connecting to the frame of theniaehine a number of levers v, v', 'vdpivoted respectively at v3, v, 'v5 and provide at their free ends with ins lv, v", 'Us respectively, that pass througi suitable holes 1n the bed-plate A7 and are adapted to be raised into the path of the teeth of the wheelst4 indicated by dot and dash lines in Fig. 2, by means of risers or projections as fu, ful", fu, on the pattern chain D, acting on the ends of suitable fingers 'vlz projecting downwardly from the levers v, 1J', v2.

The arrangement and disposition of the risers on the attern chain and the pins for engaginvv with) the toothed wheels will depend, oiD course, upon the particular changes to be made in the thread during the knitting operation. In 'the present instance` the risers and pins are so disposed that in knitting the -toe one thread is-em loyed. Upon passing to circular work for tlie foot portion the pattern chain is moved to bring other risers into position, to lift the pins into the path of movement of the toothed wheels, and effect the removal of thethread from engagement with the needles and the substitution of a lighter thread of medium weight. This thread is continued to be knit until the heel pouch is reached when the pattern chain is again moved, eHecting in a like manner a change from this medium weight thread to the previous heavier thread used in the toe portion. On completion of the toe pouch and just prior to commencement of circular knitting for the ankle portion the attern chain is again moved, bringing otiier risers into position to again effect the change of thread. -Prior to commencement of the ribbed leg portion the pattern chain is again moved to bring other risers into thread of the series is introduced.

It is desirable in making the change of thread at the various stages required tgintroduce the previously inactive thread prior t"the withdrawal of the knitting thread, and to this end it is necessary so to operate the thread-guides in their changing movement as to throw in the idle thread for several stitches prior tow-ithdrawing the knitting thread, and to do this it is necessary to provide each toothed wheel with a separate series of actu ating pins.

In the present construction there are three thread-guides provided, and the toothed wheels (Z13 for actuating the said guides to effect a change of thread are arranged at different distances from the center of the cam cylinder, and the pins for actuating said toothed Wheels are likewise arranged in three concentric circles corresponding to the varying radial distance of the toothed wheels.

By a proper arrangement of risers on the pattern chain D it will be evident that the actuating pins for the toothed wheels may be thrown into position as desired, but inasmuch as the change of threadis to be effected after several stitches of the previously inactive thread have been made, it follows that a single set of pins, such as '06, fv", (Us, for the toothed wheels will not be sufficient. Other pattern-controlled pins, such as '015, o16, t" are therefore disposed in the circular series of pins so that the timing of the change of thread may be accurately controlled.

The toothed wheels are each provided with two cams, one of which controls the operation`of the thread guides and the other the operation of the thread catchers. Each cam has two parts. Iii the case of the cam for the thread guides, one part controls the movement of the thread guide into thev needle-feeding position and the other the movement of the thread guide into the position where the thread is not knitted. In the case of the cam for the thread catchers, one part controls the movement of the thread catcher into and the other the movement out of the thread catching or clamping position. As will be pointed out, each toothed osition',` and the lightest wheel carrying the two cams is provided with two long teeth one for each movement of the thread guides and catchers into and out of position. These teeth are operated by striking against adjustable stationary pins. Each toothed wheel is also provided with shorter teeth by which the toothed wheel is positioned so that the long teeth may strike at the proper time the stationary pins, and since in the machine illustrated the cam cylinder makes two rotations to one moveme'nt of the pattern surface, two of the shorter teeth are provided for each long tooth. The shorter teeth are of such length as to clear the stationary pins, and are operated by striking against movable patterncontrolled pins which are projected at the required times into the path of the toothed wheels. I

Each of the toothed wheels is provided with a number of teeth, best illustrated in Fig. 9, two of which teeth at opposite sides are prolonged to engage when in their lowest position with suitable stationary pins as 190, 191, 192 on the top-plate of the machine.

In order to further provide for'turning the toothed wheel at desired times we pivot upon the machine frame an additional lever 'U18 similar to the levers fu, o', u2 already described, and having a detent finger '01 adapted to engage a suitable riser on the pattern chain D, and projecting from the end of said lever 'U18 we provide two pins v2", '1121.

The disposition of the pins and risers, herein specifically referred to, constitute simply a disposition of such parts for the use of three thread guides, as contemplated in the present illustration of the invention, and such general disposition of pins is necessary by reason of the relative location of the toothed wheels t13 which renders it at times necessary to operate at first the forward'or lower wheel, and then one of the following wheels to effect the desired change, and :at other times to operate first one of the wheels 1513 to the rear and above the lower 13 and thereafter to operate the forward one of said wheels.

The general disposition of the risers to effect the desired change in thread and the location and disposition of the pins defining properly the operation of the toothed wheels with respect to each other, is a matter within the ability of anyone familiar with knitting machines, and need not be further described herein.

It will readily be seen that the position of the movable pins, 'which are controlled by the risers on the pattern surface, and the position of the stationary pins, depends upon the timing of the machine and upon the particular point at which. the desired thread is to be introduced into the web, or taken out therefrom. The positioning and timingl of these pins will, therefore, be largely at the functions.

' has ceased knitting.

While" the pis 190, 191 and 192 have been termed the stationarypins they that they are pins operatedby therisers. Theymay, owever, -be removed andreplaced in .any desired position lto erforrn' their desired' The set o pins 1J, o"Y and vscare chieily 4necessary to secure the roper operation of the4 toothed4 wheels wit respect to each other when 'it is desired, as usual, to insert the newfthread .before the old thread .The threewheels are ed :one ahead of the other e distance apart, and by necessarily arran anda considerab 4the use 'of :these pins necessary relative operation' ofI the wheels can more readily be secured. a l

The movable pins v" and ou are es ecially d ed forY use where a change of t ad 1s ma. e' during reciprocating knitting, as at the toe or heel portion. They will be'arranged articular wheels whose threads are-desire to be changed, and if it were not for-them the thread. could not be changed during reciprocating knittin where the toothed wheels -are not carrie clear around over the various pins, but are obviously oscillated back and'forth in their 'circular path and it is obvious that two movements of the toothed wheels by the short teeth striking against the movable pins are' necess to osition the. wheel so that the long tee will e struck by the stationary. insn e case of rotary knitting. In the machine-as hereindesigned the pattern chainD is'moved once-to every two revolutions ofthe c'am cylinder B, which carries the toothed wheels, and thereforethe toothed wheels will lass twlce overthe pins as they are ositioned y the risers on the attern suracefor any-viven position. e arran ement of the llong and short teeth on t e toothed wheel, as shown in Fig. 9 of the drawingi is rendered 'necessary for this reason.

the4 direction of rotation of the cam cy der'. is indicated b the arrow thereon.` AThe three toothed w eels are indicated in-'dotted lines, and marked 1t", 2t", 319. -Assumeas a simple 'condition that the .knittin is being done by the .thread con-- trolled the toothed wheel Bt" and that it is desire todro this thread out and substitute the threa controlled by the toothed wheel 1t", but that this latter thread shall be inserted before the former is thrown out. vThe risers on the atternchain would be are evate the pins Iu* andv,

In the case under consideration the-thread controlled by the wheel ltt'f-wouldV be out. of operation-'and would accordi ly be put into operation b'y the pin 190, an the thread controlled by the wheel 3i being-in 'o eration would be put out of operation by t e pin 192.

OnA the second rotation o the cam cylinder past the pinsv, o, the short teeth succeeding'the long teeth would be struck and the toothed wheels given another sixth revolution to place' them position for a repetition of the movements describedand then the pins v and v would"be lowered by the of the pattern-chain so as not to be struc by the toothed wheels upon subsequent revolutions of the cam cylinder until another change was desired.

In res'lirocatng knitting, the toothed wheels obviously not pass twice in the same direction over the variouspins, hence the additional set as o, vn is necessaryto give the three movements to the wheels.
